1769-PB4 CompactLogix DC Power Supply 4A/2A | Allen-Bradley

The Original New Allen-Bradley 1769-PB4 is a DC input power supply module designed for the CompactLogix 1769 system architecture. It converts 24V DC input into regulated 5V DC and 24V DC outputs to power CompactLogix controllers, I/O modules, and other 1769 series components. This power supply supports up to 8 I/O modules on each side of the power supply, making it suitable for scalable automation systems in manufacturing, process control, and material handling applications.

Core Engineering Highlights:
24V DC nominal input (19.2–31.2V range) | 4A @ 5V DC + 2A @ 24V DC output | 100W power output | 4A 5V power supply provides 2A to each side | Supports up to 8 I/O modules per side | 0°C to 60°C operating temperature | DIN rail or panel mount | Conformal coated version available (1769-PB4K)
